SMART METERING PROGRAM
Utility Case Study BC Hydro Smart Meters
Kai Hui Director of Technology
THE GRID IS THE BACKBONE OF OUR ECONOMY
Powers your homes lights, appliances, personal technology
Powers industry mills, mines, manufacturing plants Powers commercial buildings malls, offices, stores, greenhouses Powers infrastructure telecommunications, data centres, cable networks, transit systems, airports
THE ELECTRICITY SYSTEM IS LARGE & COMPLEX
Generation 41 Dam sites, 30 Hydro facilities and 9 Thermal units
Transmission
18,000 km of Transmission lines 260 substations, 22,000 steel towers
One Control Center Consolidation of 4 regional systems (including back-up)
Interconnect to Alberta and US
56,000 km of Distribution lines Approx. 900K poles, over 300K of transformers Serve 17 Non-integrated areas 70% of these customers clustered around the 49th parallel (in greater Vancouver and Victoria)
Distribution
Approx. 1.9M electric customers
Equal to the area of California, Oregon and Washington state combined

WHY DO WE NEED TO MODERNIZE?
Our infrastructure is aging Investments in our electricity grid have not kept pace with todays global economy Most recent BC Hydro generating facility completed in 1984 System of electro-mechanical meters hasnt been upgraded in 50 years Demand on our electricity system is growing 50% more electricity over next 20 years Smart metering is the first step to a modern grid A more efficient system will save energy and money keeping Hydro rates lower than they would be without the upgrades.

SR IPv6 3.7 EFT
IPv6 1.0
Cisco offers IPv6 capability and experience to move into next generation mesh IP routing protocols Security built directly into network layers versus Itron application specific security which results in a more efficient, effective security implementation. Supports secure peer-to-peer traffic Enables Quality of Service (QoS) on the Smart Metering network to differentiate and prioritize different traffic types (metering traffic versus distribution automation traffic versus mobile workforce traffic as an example) Allows network to be a carrier of multiple applications without having to traverse though smart metering head ends, including water and gas meters on isolated networks. Superior traffic classification, congestion management and traffic conditioning Cisco collector supports IEEE1901.2 PLC for hard to reach meters
